Definitions

  • the present invention relates to an interim storage facility for radioactive material, in particular for containers with a sealing and shielding function for irradiated fuel elements from nuclear reactors.
  • Irradiated or burned-off fuel elements and highly radioactive waste must be stored temporarily after their use in the nuclear reactor until they are reprocessed or disposed of. This takes place in NaB or increasingly also in dry stores, which have to be designed accordingly.
  • the fuel elements e.g. T. in cans, preferably stored in so-called storage racks.
  • the warehouse buildings are designed to withstand external influences such as earthquakes, aircraft crashes, cooling problems and other events.
  • stores are also known in which the fuel elements remain in combined transport / storage containers after they have been transported. Since the shielding function of the containers is not sufficient due to the accumulation of containers in such a warehouse, the warehouse must still have additional radiation-shielding properties.
  • a major disadvantage of the interim storage facility described is that it consists of relatively large-volume buildings which have to be constructed in a costly manner and whose demolition can be difficult and involves considerable effort when it is decommissioned. Building expansion options are also limited. The protection against external influences is very limited with this design, the protective function must be fully taken over by the transport / storage container, which means a corresponding complex construction of the container.
  • the present invention was therefore based on the object to provide an interim storage facility for radioactive material, in particular for containers with a sealing and shielding function for irradiated fuel elements from nuclear reactors, which is inexpensive, quickly - adapted to the respective requirements - converted or expanded and dismantled without particular difficulties and can be rebuilt elsewhere.
  • the bearing consists of one or more bearing elements which enclose the container, the bearing elements being composed of tube sections which are round or angular in cross-section and placed on top of one another and a cover.
  • the pipe sections are preferably made of concrete.
  • Transport / storage containers (2) with cooling fins (3) and trunnions (4) are surrounded on a base plate (1).
  • the entire structure is covered at the top by a fitted cover (6).
  • the cover (6) expediently also consists of concrete, which, like the pipe sections (5), can be reinforced. It is particularly advantageous if the cover (6) protrudes from the concrete segments (5) for weather reasons. Also particularly favorable is the design of the tube sections (5) as cylindrical jacket-shaped circular rings, and the use of radiation protection concrete in the event that the containers (2) only have a partial radiation protection function.
  • the wall thickness of the pipe sections (5) is about 0.25 - 0.5 m for well-reinforced, highly compacted concrete when storing combined transport / storage containers.
  • the pipe sections (5) can be both annular and have an angular configuration, such as. B. a square or a hexagonal shape.
  • the pipe sections (5) can also be made in one piece or be composed of several individual segments joined together. The height of the individual pipe sections (5) is subject to change and only depends on the manageable weight and the transport options.
  • the concrete rings (5) can be stacked on top of one another using simple lifting equipment using hooks or handles (7), the end faces (8) of the rings (5) having fitting parts (9, 10) formed in a tongue and groove manner, which ensure a secure, stable fit .
  • Other fitting parts and shapes are also possible.
  • the lid (6) also has devices (7) for handling. At least in the lower ring (11) and in the upper ring (12) under the cover (6) there are preferably openings (13) which ensure the inflow or removal of cooling air in a suitable size.
  • the openings (13) can be protected by grids or screen mesh (14). In the case of radioactive inventory that has severely decayed, however, the openings (13) can be dispensed with partially or completely.
  • Centering devices (15) adapted to the respective container type can be located within the pipe sections (5), which firstly provide for the central accommodation of the containers (2) within the space (16) formed by the pipe sections (5), and also as anti-tilt protection for serve the container (2).
  • the same function has distance Holders (17), which are pushed, for example, with recesses under the trunnions (4) or placed on the upper edge of the cooling fins.
  • the centering device (15) is fastened on the base plate (1), but it can also be embedded in the base plate (1).
  • the pipe sections (5) can of course also consist of other materials, such as. B. made of steel.
  • One or more containers (2) with radioactive material can be accommodated in the interior (16) of the bearing elements (23) formed by the tube sections (5), arranged side by side or one above the other.
  • Fastening elements (19) are located on the outer circumference of the pipe sections (5), to which connecting elements (20) can be mounted for mutually fastening or fixing the spacing of adjacent bearing elements (23).
  • the bearing group formed from a plurality of bearing elements (23) advantageously contains an additional one Stability, e.g. B. against earthquakes.
  • the connecting elements (20) also secure the necessary supply of the cooling air flow as spacers. It is expedient to create bearing groups from two-row bearing elements (23), but other group arrangements are also possible.
  • the additional removable cover of the groups formed is particularly advantageous with a strong concrete plate (21), which in some cases can also be provided with a damping protection against large, falling objects.
  • the concrete slab (21) provided with eyelets can be handled by suitable lifting devices (24).
  • suitable lifting devices 24
  • the concrete slab (21) lies directly on them or, in order not to hinder the rising cooling air, on supports (22).
  • the concrete slab (21) can also be interspersed with suitable chimney-like channels or similar devices.
  • the interim storage facility according to the invention is particularly suitable as a free storage facility. It is quick to assemble and disassemble, and its variable options also allow it to be quickly adapted to different requirements. All parts are - because there are a large number of building blocks - cheap and can be produced with constant quality and would be standardized, even with regard to a standardized Camp. Two-storey or multi-storey storage can be carried out on a case-by-case basis. It is advantageous if the bearing elements (23) are surrounded by radiation shielding barriers for safety reasons (lateral protection). Advantageously, this uses bearing elements (23) or pipe sections (5), which are filled with non-radioactive bulk material (25), such as, for. B. sand are filled.
  • the bearing elements (23) according to the invention can also be easily installed as intermediate storage in caverns and in existing nuclear facilities, as well because of the mobile construction also for temporary unpredictable intermediate storage of transport containers.
  • the bearing element (23) can only contain one tube section (5).
